Two Problems: New terrain editor fill tool, fill mode dragger not working properly; target materials list disappears or is never rendered

Problem

There’s two issues with the new terrain editor.

  1. When using the fill tool’s fill mode, the dragger will not move when snap to voxels is checked. It highlights when you mouse over it, but it will not move.
  2. At times, the target materials list within the fill tool disappears and reappears, or disappears and will not reappear.

Expectations

I expect the dragger for the fill tool’s fill mode to be movable for when the snap to voxels option is checked.

Missing materials to fill with.

Missing target materials to replace with.
